Liz, you've forgotten already? Condoms are your best friend. They're for carrying water (You can get a gallon in a condom if you shove it down a shirt sleeve to stop it bursting)and for keeping water and dust out of delicate places. And, as any colour Sergeant in the British Army will tell you, they are NEVER to be used for anything else! Which begs the question; why do pubs with a perfectly good off-sales service still sell condoms in the bogs?
